A wildlife biologist wants to determine the mean weight of adult red squirrels. She captures 10 squirrels she believes to be representative of the species and weighs them, finding a mean of 12.32 grams and a standard deviation of 1.88gm. Assuming these squirrels can be considered a random sample of all red squirrels which of the following formulas gives a 95% confidence interval for the mean weight of all squirrels? A) 12.32+- 1.96(1.88/root10)
B) 12.32=-2.228(1.88/root10)
C) 12.32+-2.262(1.88/root10)
D) 12.32+-2.228(1.88/root9)
